Braille text in blender
I know nothing about braille but this should be as simple as grabbing a suitable font and extruding it. I tried braille normal from fontspace. Once in Blender, add a Text object, edit it as needed and then navigate to the .ttf font file under Font, the Regular input should be enough.



One you are satisfied, you can edit the Extrude slider for the depth or convert it to an object and play with it some more (booleans etc).
